The device contains a measuring electrode in the form of a metal plate, which is connected to an amplifier circuit. If an object with a significant electrostatic potential moves through the detection area of the sensor plate, the influence of the electrostatic field emanating from the potential leads to a charge transfer in the amplifier circuit.
The device electronics can thus record the charge displacement as a current. If the set threshold value is exceeded, this can be signaled optically. The switching signal can be picked up via a relay interface. Both the switching status and measured values can be output via an RS485 interface.
The RS485 interface can be used as a variable source of information.
The application can range from optical signaling in the form of a traffic light to an EDP system.
